Air Quality � LBH has extensive Air Quality monitoring programme: 8 continuous monitoring stations & 60 diffusion tubes; � Air quality has shown steady improvement generally, however exceedances of NO ₂ remain (Brentford, Chiswick, Gunnersbury); � No exceedances of PM, but no safe threshold limit)! � NO ₂ exceedances of EU limit value are mainly associated with high volume of traffic; PM prevalent on roads (A315, A316, A406, A4, A312 & M4) dominated by diesel vehicle fleet & fright; � LBH AQ monitoring provides robust evidence for where planning & mitigation measures need to focus 2
